The suspect then shot and injured several officers who approached the classrooms, and they retreated to a hallway outside the rooms. Further, the doors at Robb Elementary were not able to be locked from the inside, McCraw said, calling it “ridiculous” from a security perspective. However, the tool wasn’t brought into the school until an hour after officers arrived and was never used, the timeline said. In all, officers had access to four ballistic shields inside the school, the fourth of which arrived 30 minutes before officers stormed the classrooms, according to the timeline. Uvalde Mayor Don McLaughlin said the district attorney for Uvalde County made the request to not release those records.
